STORAGE DEVICE.

Application filed September 15, 1922. Seria1 No.l $8 ,419.

To all whom it may] concern:

.Beit known that 1,.WILL1AM Morm'r, a citizen of. the UnitcdStates, residing "at 7 and exact description.

; This invention relates to the storage of fragile or lump material, to a-void brealrage thereof and has particular value inthe sort ng and storageof lime. Lime'com ng from the kilns comprises a mixture of fine'and coarse particles or lumps, and the latter ing and shipping, that hreakage of "the lumps. or coarse particles be 'preyented as fanas possible if a maxlmum market price is to be realized. An object of theinyention is toprovide improved means for thesorting t and storage of lime, withhwhiclrthe breakagevof the coarselumpsor particles is refi duced to a ininimum; witlrwhich the sort;

ing and storage is accomplished in a simple;

convenient, efficient and expeditious" manner, and which is. simple, and inezipensiye in -constructlon and'operat on. Other ob ects 1 followingdescription ofan embodiment of f the invention and the novel 'featuresl will be particularlypointed out in claims.

In, the accompanying [drawings Fig. is a sectionalelevation through a ,sorting, and storage deyice constructed in accordance with this invention and taken.

siihstantially along the line aQ-b oflligthe a .f Fig. 3 is a transverse sectional; elevation; j adapted toscrape anymaterial whichis deposited upon the wall or platform 8 along of I a portion of thesame; and

Figaifi: is a sectional elevation of a portion" of the same, taken substantially along the line 4- 1 of Figure '3.

In the illustrated embodiment of the in- ,Vention, a plurality of columns 1 are tied together by cross columns 2 and tie rods 3 to t form a suitable supporting frame or structure for thestorage] bin proper. The. bin

proper is formed of suitable sheet metal 1 ywhich is dependingly supported from the ,upper ends of the columns, and of sheet ,metal 5 which extends above the upper ends of. the intermediate columns, forming an air and water ti'ght' roof or cover." The walls formed by theshee-tmetal aare're'infdrced "at the ends streams channels" or 'I Fbeams .6 whlch extend cross wise or; the hit ned transyerse cross"sectibffth shape ofa catealso be used, as illustrated. A partiti'om or wall 7 isldisposed across the interiorof the brings a higher market price, than the fine" b i lime. I It is ery desirable thatin storing the lime from the kilns, preparatory to packin inaniiicl-incd pos'iti'on-so as"to divide the" interior of the bin'into two storage compart1r1ents" l'-and '15. A Waller platform 8 jeirtends froni'the upperend" of the" inclined partition"? substantially horizontall across the upperendof the compartment Ajwhich 'eztteiids beneath "the inclined wall "or 'p'artition. The compartment B- whichis formed above. the "inclined' partitionisopen at the top for its er'iti're length and forawidth at j' arrange.cl adjacent theends of thelhinpand .Qand advantages will be apparent from the the wheels support and drive a pair of spaced Qen'dless'belts 13 that extendlengthwise' of 'the bin over the open face of the compartment B and over'andinclose'proximity to movement ofthe belts. The belts=a're-connected upon theirlouter' faces with transversely extending scrapers 15 which "are the same and over and upon the upper face of the inclined wall or partition 7. Iheendless belts, scrapers, and sprocket wheels thus form an endless carrier device.

A screening device 16" is mounted upon guide devices 17 for reciprocatingmovement in a direction either crosswise or" lengthwise of the'bin and has an inclination towards the platform 8; The screening device is provided with a suitable reticulated plate or screen 18Whi'ch isspaced above theimperforate bottom wall and which is adapted to permit of the passage therethrough of the finer particles of the lime, and to shift the coarser particles along the same and deposit them upon the platform 8 between the upper and lower stretches of the endless carrier device. The lower wall 19 of the screening device terminates before reaching the platform 8 and discharges the finer particles of lime carried thereon through chute 20 into the storage compartment A of the bin. The coarser particles which are deposited upon the platform 8 by the screen 18 are carried by the scrapers 15 along the platform'and over and upon the upper face of the inclined Wall or partition 7, and the coarser particles so deposited will slide or ,roll down the inclined partition at a comparatively slow speed so that when they come to rest, it will not be with sufficient force to cause a breakage thereof into line particles.

In order to reinforce the inclined partition and also to provide additional resistance to the rolling or sliding of the lumps or particles down the inclined partition, I may provide upon the upper face of the partition cross strips 21 which may be in the nature of channel or I-beams which extend horizontally across the partition at different levels thereon, so as to stiffen the inclined wall and also catch the lumps or coarse particles and retard their movement down the partition. As soon as a layer of the coarse particles or lumps has been formed upon the inclined partition, the carrier device will continue to scrape the particles from the platform 8 over and upon the surface of the layer, and the surface of the layer will offer resistance to the rolling or sliding movement of the newly deposited lumps or particles sur'ficient to present rapid movement down the same and upon the bottom wall. The carrier device will continue to deposit the material upon the upper end of the layer surface and as the layer surface progresses lengthwise of the bin the carrier device will continue to deposit the coarser particles progressively thereon until the bin is entirely filled.

The screening device 16 may be operated in any suitable manner, but as illustrated is connected by a. suitable link 22 to a crank 23 that is continuously rotated by means of a pulley 2-1 and a belt 25 or by any other suitable source of power. The screening device will, therefore, be reciprocated back and forth continuously and when the lime is deposited upon the screen 18, the line particles will pass through the same and fall upon the plate 19 and the coarser particles will be shifted along the screen by the reciprocating movement and deposited upon the platform 8.

A suitable elevating device 26 may be provided adjacent the bin for carrying the lime to a point above the screening device 16 and depositing the same through a chute 27 upon the screen 18. The lower wall of the bin is provided with discharge chutes 28 at each side and extending along the length of the bin, and these chutes are controlled by valve or gate members 29 which may in turn be actuated to open or close the same by suitable operating members 30.,

In the operation of the device, the lime from the kilns is carried by the conveycr 26 to point above the screening device an deposited into the latter through the chute 27. The lime falls upon the reticulated plate or screen 18 which is being continuously reciprocated by the rod and the crank 23. The. movement of the screen causes the finer particles to pass through the holes in the screen and fall upon the bottom plate 19 which inclined towards the chute 20. The reciprocations of the screening device cause the particles from the plate 19 to slide or roll down the same and fall through the chute 20 into the storage compartment A. The coarser particles or lumps which cannot pass through the holes in the reticulated plate or screen 18 are caused by the shaking movement to roll or slide down the screen and fall upon the platform 8.

The scrapers 15 of the endless carrier device in moving across the platform 8 carry the deposited particles along the platform and over and upon the inclined wall or partition 7 until an inclined layer of the particles is formed thereon and upon the sun face of this layer progressively as the layer progresses across the bin. It will be noted that during this handling, separation and storing, that the coarse particles or lumps are at no time given any considerable momentum or stopped abruptly, with the result that there will be little or no breakage of the coarser particles. The lime is withdrawn from the bin as desired for packing or shipping by means of the discharge chutes 28 which are controlled by the suitable gates 29.

While I have explained the application of the invention to the handling, sorting and storage of lime for the purpose of demonstrating the nature of the invention. it will be understood that the invention is applicable to the handling, sorting and storage of other similar fragile lump material and such other materials are to be comprehended within the meaning of the terms used throughout the specification and claims. It will also be obvious that various changes in the details and arrangement of parts herein described and illustrated for the purpose of explaining the nature of the invention may be made by those skilled in the art yvithin the principle and scope of the invenliil) I claim: I p I 1. In a sorting and storage device, a bin With an inclined partition dividing it into tvvo compartments, a substantially horizontal Wall extending from the upper end of the inclined partition, a screening device arranged to separate the material into relatively coarse and line particles and to discharge the finer particles of the material directly into the compartment extendin beneath the inclined partition and the coarser particles upon the horizontal Wall, and means for carrying the material from the horizontal Wall over upon the upper end of the inclined partition and upon the upper end of the inclined layer of material formed upon the partition progressively across the compartment.

2. In a sorting and storage device, a bin with an inclined partition dividing it into tWo compartments and a Wall extending from the upper end of the inclined partition at least partially over the compartment extending beneath the partition, an endless carrier extending over the Wall, inclined partition and the compartment over the partition, and having means for scraping material deposited upon said Wall over upon the-upper end of the inclined partition and then upon the upper end of the inclined layer of material formed upon the partition progressively across the compartment, a screening device arranged to separate the particles into fine and coarse particles, deposit the line particles in the compartment extending beneath the partition and the coarse particles upon the Wall to be carried over into the other compartment.

3. In a sorting and storage device, a screening device for separating the material into coarse and fine particles, a storage chamber into which the fine particles are deposited, av platform upon which the coarse particles are deposited, a second storage chamber having an inclined Wall connecting at its upper end to the platform to form an inclined extension of the same, and mechanism for moving the coarse material along the platform over upon the upper end of the inclined Wall to form an inclined layer thereon of the material and then upon the upper end of the inclined layer of the material Which is formed progressively across the second storage chamber.

In witness whereof, I here-unto subscribe my signature.
